Lette/rs Patent No. 93,438, dated August 10,1869.

f IMPROVED HORSE-P OWER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern horse-power, whereby the motion imparted may be readily changed from right to left hand without changing the direction iof draught, as will be more fully described hereinafter.

In the drawings- Figure 1 is a plan View of my invention;

Figure 2 is a similar view, inverted,'the masterwheel being removed;

Figure 3 is a'longit-ndinal vertical central section, through line as-x, lig. 1; Aand Figure 4 is a detached view of one of the 'masterwheel pinions. A

To enable others skilled in the art to make and use my invention, I will now describe fully its construction and' operation.

AA represent the longitudinal beams, which, with the cross-beams A A1, form the foundation of the machine.

A2 A2 represent additional cross-beams, between which is a longitudinalA central beam, supporting theinetal plate A, in the centre of which is the bearing of the master-wheel B, and at the end the bearings of the bevel-wheels B.

The former, B, consists of an annular' rim, provided with suitable drauglitattachments b, and the cogs b on its inner face, which mesh withthe theshafts of the bevel-wheels B.

D represents the' main shaft, which runs parallel with the beams A, and has suitable bearings in crossbeams between the same. l

The shaft D lis provided with four bevel-pinions, d,

two for each of the bevel-wheels B', which pinions are so arranged that only one` can come in contact v`with each wheel at the same time, the others projecting beyond the opposite sides thereof. The shaft, however, admits of a suliicient longitudinal motion, to change the position -of the pinions at will, and, by sliding it Ain 011e direction, two of the pinions d will engage with one side cfs-each of the bevel-wheelsB; and when the shaft is moved in the` opposite direction the remaining two will engage with the opposite sidesof the same, thus reversing the motion of the mechanisni without changing the draught. v

E E represent stops or clutches, near the two midpinions G on d dle pinions d, which are pivoted to the sides of the beams E', and are providedl with the curved ends e, which are of the same width as the pinions d, and are operated by the handles c.' Their position is such that when one of the pinions d is pushed out from one of the beams E' the clutch is pushed up between the pinion and the beam, thereby preventing the same from sliding back until the stop is removed.

The other stop is located in the opposite side of the shaft D, and works in. a similar manner.

The master-wheel pinions O are loosely sleeved on the shafts of the bevel-wheels B', and are provided with the teeth or projections c, which engage with the arms b of the bevel-wheels, and are revolved thereby.

F F, Ste., represent friction-wheels on the beams A A, in which the master-wheel runs, and f f, similar wheels, to keep the bevel-wheels B in position.

, The shaft D is provided with suitable coupling-ears D' on both ends.

The operation of' my invention is as follows:

The master-wheel being revolved in any'suitable manner, operates the pinions C and bevel-wheels B', which, being'in connection with two of the pinions d, cause the shaft D to revolvein adirection corresponding to the position ofthe pinions d their position being altered by the above-described means, the motion of the shaft is reversed. 4

By this arrangement, the wear of the cogs can be equalized on each side, making themachine much more durable. l

By the construction of the pinions C, they can be easily removed when wom'out, without the necessity of removing the bevel-wheels, the pinions being subjected to the` greatest amount of wear. They also admit of a slight play on their bearings, which relieves, in a measure, any sudden strain.

I am also enabled to attach conpling-shaits at both ends of the main shaft, and, if necessary, to operate two separate machines. l

Having thusfully described my invention,

What-,I claim as new, and desire to secure by Letters Patent, is-

1. The-sliding shaft D, providedwith four pinions, d, and coupling-ears D at veach end, substantially as and for the purpose set forth.

2. In combination with the above, the stops E E, substantially as described.

This specification signed and witnessed, this 14th day of May, 1869.

JOHN HEUERMANN.
